This invention relates to a new and improved extractor adapted to be combined with a washing machine or other device.

' An object of this invention is to provide tractor which may be positioned-above a vat or washing chamber and yet allow access to the vat or chamber without necessitating the removal of the extractor.

Another object of this invention is to provide an extractor which utilizes an improved type of sup- Fig. 5 is an enlarged sectional view of another type of extractor supporting means which may be used in my invention;

Two methods-of supporting the centrifuge are shown. One in Fig. 4 where the track is secured to the troughshaped centrifuge as by bolts 23 and may be rotatably supported in the bearings. I! which may be secured to the outer wall 25 of the drying chamber as by bolts 21. In another construction shownin Fig. 5 the track may be secured by flanges 29 on the drying chamber and bolts 3|. bearings [1 may be secured to the centrifuge as shown with bolts 33. An oil drip plate 35 maybe secured to the outer wall of the drying chamber by suitable means.

Holes 3! in the drying chamber may be provided to allow any lubricant which might collect in the oil drip plate to escape to the outside.

Various means may be employed to drive the centrifuge. In the drawings Ihave shown a V-belt 39 which may cooperate with a suitable stop valve which may be employed in my inven- Fig. 9 is a sectional view on line 9-9 of Fig. 2;

Referring now to the drawings, the numeral l indicates a washing chamber provided with an agitator or paddle 3 and provided with a side wall 5. A drying chamber l'may be secured to the washing chamber. walls as by rivets 9. A centrifuge II with a large or substantial opening I! therethrough which may be saidto be of annular trough shape may be rotatably supported within the drying chamber as by a trackli and bearings II. It may be desirous and advanta, geous to construct the track of a resilient material such as rubber which may have ahardened portion' II formed integral with a soft portion II.

groove 4| in the drying chamber to rotate it. The belt is driven by means yet to be described.

Various types of centrifuge may be used with this invention. With the type shown in the drawings, the outer wall 43 may be corrugated as shown in Fig. 14. Slots 45 may be provided, as

shown, in the corrugations with the axis of the slots inclined in the direction of rotation of the centrifuge. If desired, holes may be used instead of slots. Thus when the centrifuge rotates in the the direction shown by arrow B, air will be drawn in through the holes to fluff or aerate the clothes. The inner wall 41 of the,centrifuge may be formed with a slope which will allow the clothes to slide into proper position around the centrifuge. This sloped wall 41 furnishes a means to dynamically balance the load in the centrifuge. If desired,

the inner wall may be provided with corrugations I r and openings therein adapted to force air into the centrifuge. The corrugations might also be useful in strengthening the centrifuge.

v A fluid passage 49 may connect the drying chamber 1 with the washing chamber. A valve 49 may be positioned in the fluid passage and may consist of valve seats 5!. a tapered valve '3 secured to a rod or stem 55. A cap." encloses the In this latter type of contruction the valve and seat. 'l'he valve stem maybe provided with a handle or knob BI and two indentations or recesses 83. A plunger 85 pressed by a spring 61 cooperates withthe recess to maintain the valve in either opened or closed position.

The V-belt 39 may be driven from a suitable shaft Il may be changed by raising or lowering the forked bearing member 8!. A rod 83 provided with suitable recesses 85, plunger 81 and spring 88 to cooperate therewith may be provided so-that the gears may be positioned in either forward, neutral or reverseposition. A splinedarrangement may be used to rotatably secure the gears I or the pulley $9 to the shaft so that the pulley 89 may remain in fixed verprovided to manually control the rotation of the shaft and hence the centrifuge. A lid 92 may be provided on the washer and may be arranged so that when it is raised the rotation of the centrifuge is stopped and it will be impossible to sus tain any injury from the rapidly rotating mem her. The apparatus for this control is shown in Fig. 13 where a block 94 with a V-shaped opening 98 is slidably mounted in a support 98. A pin I08 is formed onthe control rod 83. A lever I02 operates in connection with an extension I04 ofthe block 94. The lever I02 is secured to a shaft I06. The shaft IDS is secured to the lid 92 so that on opening the lid the shaft I06 rotates and moves the block 94 to force the pin I88 into the small end of the V-opening, thus moving the control rod to stop the centrifuge.

'The lid or cover 92 is provided with openings 7 I08 which allow air to be drawn hand through the clothes as previously outlined. An inner lid I III is provided and will allow access to-the washing or agitating chamber or vat without raising the large lid 92. Hinges 2 are provided for the lids. Louvres Ill are provided on the stationary portion 8 of the lid and provide means'fo'r the exit of air from the centrifuge.

. A water outlet III may be arranged above the centrifuge and consists in a; pipe 8 provided with holes I20 which cause the fluid in the pipe to be sprayed onto the contents of the centrifuge.

The pipe H8 is connected to a mixing faucet I2I through pipes I22. Pipes I24 and I28 are In the machine which I have described, clothes may be placed in the washing chamber without removing the centrifuge and thoroughly cleansed after which they may be placed in the centrifuge position although the vertical position of the gears I5 may be changed. A handle 90 is which may be first rotated in the direction to expel the water therefrom. The fluid passage from the drying to the washing chamber may be opened during this process to allow the soapy water removed from the clothes to be returned to the washing chamber. The clotha may then be rinsed by opening the mixing faucet E20 and allowing water of the desired temperature to be sprayed onto the clothes in the centrifuge. If desired the clothes may be treated with steaming water in this manner. The direction of rotation of the centrifuge may then be reversed and air drawn through the centrifuge to aerate or flufi them. After being centrifugaliy dried, the clothes may be removed from the dryer. Rinse water may be allowed to pass from the drying chamber through the drying chamber drain. Since the opening in the centrifuge is large, the agitator may he removed through the opening without removal of the centrifuge. Likewise, clothes may be placed in and removed from the washing chamber while the centrifuge is in operation.

Since the drying chamber is located above the washing chamber it is not newssaryfto employ a pump for pumping the water back into the washing chamber when desired. This arrangement also makes it possible to spray water over the clothes, in the centrifuge and simultaneously drain such water out.

While I have illustrated and described but one embodiment of my invention, it will be apparentto those skilled in the art that various omissions,

additions, substitutionschanges and modifications may be made in the method and apparatus illustrated without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim as my invention:

1. In the drying chamber of a combined washing and drying machine, a reversible annular trough-shaped centrifuge, a track secured to the outer periphery of the centrifuge, a drying chem"- her, a set of bearings secured to a wall of the drying chamber and cooperating with the under sidement of the centrifuge and driving means to rotate the centrifuge.

2. In the dr g chamber of a combined washin and drying mac e, a reversible annular troughshaped centrifuge, a track secured to the outer provided for a hose'connection from hot cold water supply lines. a

A drain m from the drying chamber is provided with -a valve 49 similar in construction with ,the valve 49 previously described. The members BI, 83, 85 and 81 may be similar to those members as previously described. Likewise the washing chamber-is provided with a drain' I30 and the corresponding valve fittings. An electric motor I32 may be used to drive the washing machine.

I'have-thus described my invention in connection witha washing machine; it might be equally advantageously employed for dyeing, bleaching, treating or other processes where a centrifuge is required.
